Description Overview This GAOTek Hydrogen Bromide Gas Analyser It is used for on-site gas concentration detection and alarm for excessive gas concentration. It can detect the concentration of various toxic and harmful flammable gases and display the real-time concentration value and standard signal output on the spot. The main detection principles are electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photo ion. It has the advantages of stable signal, high sensitivity and precision, and the flameproof wiring method is suitable for various dangerous places. Features Explosion-proof, anti-lightning, anti-static, reverse connection Anti-emit, EMC electromagnetic interference Anti-pulse surge current impact Three-wire system or four-wire system 4 to 20ma standard signal output It also has a standard bus system RS485 output (RTU format) The wireless transmission method can be 433, GPRS, Wi-Fi, methods Standard infrared remote control can be operated in dangerous situations without opening the cover Each unit can be switched to each other Automatically track the zero point to prevent drift It can communicate with the computer Monitor the concentration of the field probe in real time Technical Specifications Detection Gas Hydrogen bromide HBr Scope Of Detection 0 ppm to 10 ppm, 50 ppm,100 ppm Resolution 0.01 ppm Detection Principle Electrochemical principles Sensor Life 2 years Detection Accuracy ≤ ±3 % F.S Linearity ≤ ±2 % Repeatability ≤ ±2 % Uncertainty ≤ ±2 % Recovery Time ≤ 30 S Response time T90 ≤ 20 S Signal Output Bus system RS485 (RTU), three (four) wire system 4 to 20mA, Optional: 0 mA to 20 mA, 1 to 5 V, 0 to 5 V, to 10 V, wireless transmission, network transmission, SMS alarm. Humidity ≤10 % RH to 95 % RH (normal) Display Method 1.7 in high-definition colour screen display on site Operating Voltage 12 to 36V DC DC, the standard power supply of a single device is 24 V, 1A or more than 1A DC regulated switching power supply Power Reference 24 V, 2.1 A switching power supply can drive 40 toxic gas detectors, or 15 combustible and infrared gas detectors Alarm Method The default is 1 channel, optional 2 passive contact (dry node) output, three-level alarm, and the alarm point can be set. On-site sound and light alarm (optional) Connecting Cables 4 to 20 mA three-core shielded cable, RS485 select four-core, single wire diameter ≥1.5mm when the distance exceeds 1000 m; the shielding layer is connected to the earth.
